Physical and chemical properties of zinc

Metal zinc, chemical symbol Zn. It belongs to Group H subgroup of the periodic table of chemical elements and is one of the six basic metals. Zinc is a white, bluish-gray metal with a metallic luster and occurs naturally as a sulfide. Zinc has a density of 7.2 g/cm 3, a melting point of 419.5 ° C, a boiling point of 906 ° C, and a Mohs hardness of 2.5, and its hexahedral crystal structure is very stable and cannot be changed, but can be strengthened. The fine grained zinc is easier to roll and draw than the coarse-grained zinc.

Zinc is not oxidized by dry air, carbon dioxide-free air, or dry oxygen at room temperature. However, when in contact with wet air, its surface will gradually be oxidized, generating a layer of grayish white dense alkaline zinc carbonate to wrap its surface, protecting the interior from erosion.

Fences, anti-theft Windows, garage doors and other profiles are made of very advanced zinc alloy steel anti-rust substrate (high strength). The use of high-tech, through 20 special surface treatment, such as hot dipping zinc: play an electrochemical protection role, electric inside and outside to prevent the substrate rust (no rust). Organic zinc epoxy powder coating: excellent anti-corrosion properties and anti-impact properties. Polyester color powder coating: UV stability, long-term anti-fouling properties and surface self-cleaning properties. Multiple color performance options (many colors and cheap).

Dongguan Hengye Building Materials Industrial Co., LTD. Zinc alloy steel anti-theft Windows are welded and fit advanced technology (simple operation). The components are made of high strength engineering nylon, whose strength and hardness are much higher than that of ordinary steel. It can withstand the tensile force of 183mpb per square centimeter, and can withstand the high temperature of 220℃ without deformation.

The company solemnly promises that the service life of Hengye zinc alloy steel profiles can be up to 30 years in harsh environments. If the surface is 3% rusted within 30 years (except man-made damage), it will be replaced free of charge.

Manufacturer suggested price, spray anti-theft window 170 yuan/square meter, imitation wood grain 200 yuan/square meter.
